IMPROVEMENT IN MOLE-PLOW.

Specification forming part of Letters Patent No. 23,745, dated April 19, 1859.

v and represented as follows:

By reference to the accompanying drawings, Figure 1 is a side elevation of our improved plow, showing its parts arranged in working position. Fig. 2 is a plan taken from the top of the plow, showing specially the arrange-- ment of its supporting and regulating trucks. Fig. 3 is an end view, and Fig. 4 a side view, of the adjustable mole. Fig. 5 is a sectional view of the foot attached to the cutter, showing the peculiar manner of its fastening.

Ais asupporting-carriage, provided with the supporting friction rollers a a, regulatingtrucks 1) b, friction-rest 0, and rotating cutter d, and also with a windlass, c, and pivoted to the beam B atf.

B is a working-beam, its after end being adjustable vertically by means of the Windlass e, and its forward end also adjustable vertically by means of the windlass g of the draft-posts p, which are attached to and form part of the sliding supports it h.

i is a eolter, made to pass through the beam B, and bolted thereto in such manner as to allow to ita slightlongitndinal play or vibration, and extending downward in a curved are the common center of which is the pivoted point at f, through the carriage A to the foot j. The lower part of the colter is made of a peculiar form, as shown in Fig. 5, to fit the step j in the footj, and is there firml secured by means of the key k.

Z is an adjustable mole, attached to the colter a by means of the clevis m in such manner as to allow easy vertical motion to the pointof the mole l. The mole l is formed with a triangular groove, l, is conicalshaped at-its heel, as shown in Fig. 3, and tapering downward and forward to its point, as shown in Fig. 4.

O is a friction-rest, arranged to afiord hearing to the colter, thus preventing strain upon the beam B, and also to facilitate the adjustment of the beam.

B is a rotary cutter, arranged in such manner as tocutand open thesnrl'ace of the ground for the passage of the coltcr i.

b b are regulating-tiucks, arranged in such manner as to prevent the plow from lateral iiiclination, and to afford support to it when the nature of the soil is such that the snp 'iorting friction-rollers sink too deeply into it.

What we claim as our invention, and desire to secure by Letters Patent, is-- Pivoting the carriage A to the beam 13 near its forward end, as represented, and in combination therewith the curved colter i, pivoted to the beam B, and friction-rest c, all arranged and operating in the manner herein set forth.

In testimony of which invention we have hereunto set our hands.
